changing a usb hid mouse into gamepad (stm32F4)

[huub8]

Hello All,

I'm trying to change the stm32f4 discovery demonstration project (a usb mouse) into a usb gamepad. But as soon as I change 09 02 (usage: mouse) into 09 05 (usage: gamepad) in the usb descriptor it stops working.
Right now the code makes it act as a usb mouse that always sends x = 1, y= 1 and the other values are 0. I have been trying to get this to work for weeks now, but without succes.

The project can be downloaded here:
**broken link removed**

The actual workspace (using IAR embedded workbench) can be found in there here:
stsw-stm32068\STM32F4-Discovery_FW_V1.1.0\Project\Demonstration\EWARM


I would be very grateful if anyone could have a look at it (since I already tried changing any of the descriptors values that I could think of).

Some idea: avr usb gamepad is open source. I think this files contains what you need.

Thank you but i need to use the library provided in the example to be able to also use the usb host function later on
